}} The Port River Expressway is a freeway-grade road. The expressway links Port Adelaide and the LeFevre Peninsula to the northern suburbs of Adelaide and major interstate routes via Salisbury Highway (A13) to Port Wakefield Road (A1) and the Max Fatchen Expressway (M20) to Perth and Sydney. The expressway is only freeway grade at the North-South Motorway, Hanson Road and Eastern Parade interchanges; the following two intersections are at grade with traffic signals installed. This has led to the route being labelled as the A9, instead of the more common M label associated with freeways and expressways in South Australia. ==Construction== The Port River Expressway was built in three stages: *Stage 1 - Was opened for traffic on 19 July 2005. It consists of a four-lane expressway link between Francis Street and the then South Road, Adelaide, now North-South Motorway; with an overpass at each of the junctions of the North-South Motorway, Hanson Road and Eastern Parade. *Stage 2 - Consists of a four lane high-level, opening road bridge across the Port River between Docks 1 and 2, linking Stage 1 at Francis Street to Victoria Road on Le Fevre Peninsula. This section opened on 3 August 2008〔 〕 *Stage 3 - Consists of a single track, dual gauge, high-level, opening rail bridge across the Port River, north of the road bridge, with connections to the existing rail system. Opened in June 2008.〔 〕 The Port River Expressway is now a major thoroughfare for freight and passenger road traffic travelling from the northern suburbs to the major port facilities of South Australia in Port Adelaide and Outer Harbor. The construction of Stages 2 and 3 was carried out by Abigroup. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Port River Expressway」の詳細全文を読む スポンサード リンク
